Garrett and Clifford M. Peters, Longview, Tex., assignors, by mesne assignments, to U.S. Industries, Inc., a corporation of Delaware Application May 16, 1955, Serial No. 508,562 20 Claims. (Cl. 166-214) This invention relates to a well apparatus wherein a valve means or other member is shifted from one position to the other by manipulation of a mechanism in a well. In another of its aspects, it relates to wire line tool-s particularly adapted to shift such valve means or member and to mechanisms for determining or indicating whenthe shifting has been properly accomplished.

.In co-pending application Serial No. 330,294, filed January 8, 1953, now Patent No. 2,804,830; there is showna well apparatus wherein a valve means or sleevelike member is shifted from one position to another, or between three positions, to control flow through one or more ports in a well conduit- In the same application, a wire line tool for effecting such shifting is described and claimed and it is a general object of this invention to provide improvements upon. a tool of that same general nature. I

In co-pending applications Serial No. 374,296, filed August 14, 1953, now Patent No. 2,790,501; Serial No. 414,924,, filed March 9, 1954, now Patent No. 2,790,395; Serial No. 449,632, filed August 13, 1954, now Patent No. 2,818,925; Serial No. 435,984, filed June 11, 1954, nowPatent No. 2,808,781; and Serial No. 484,164, filed January 26, 1955, there are described various other arrangements of valve means or other members for effecting variouswell operations including not only the control of flow through a port in a well conduit but also the setting of a packer and the like. In each of these cases, the valve means or other member is shiftable and hence it is desirable to provide a tool for accomplishing such shifting.

In the specific embodiments of. the apparatus described in the above applications, a sleeve is shiftable axially of the well conduit by a wire line tool and, as a matter of practice, wire line jars are frequently used in conjunction with the shifting tool in order to apply a jarring action to the sleeve. When the sleeve is to be moved downwardly, the shifting tool can'be supported by the sleeve while the wireline is manipulated to effect operation of the jars.

However, when the shifting tool is to move the sleeve upwardly, any slacking oif of the \wire line tool to operate the jars normally results in the shifting tool dropping away from the sleeve so that a proper jarring action cannot be accomplished but instead, the shifting tool the sleeve to deliver an impact blow thereto.

, In the shifting tools specifically described in the above applications, there is provided at least one dog which engages the sleeve to move it upwardly after which a frangible connection between the dogand the tool housing isxsevered to permit the dog to retract to free the tool to be removed from the hole. The frangible connectionis of such nature that a considerably greater upward pull on the wire line is required to sever the connection than to causev the sleeve to shift upwardly. As a result, pthere is a fairly positive assurance that the sleeve has. been properly shifted to its upper position.

downwardly, dogs are employed to engage the sleeve and then the entire tool is itself reciprocated and rammed into.

Ice

is jarred or pushed downwardly. With such an arrangement, it is diflicult to be positive that the sleeve has been shifted downwardly as far as desired since there is no releasable connection or the like which given an operator a positive indication of proper sleeve shifting as is the case whe'n the sleeve is moved upwardly. As a result, it has sometimes been the practice to jar the tool downwardly with a great deal more vigor and for a longer period of time than is actually required toshift the sleeve. It would be highly desirable to possess anindicating tool to positively determine when the sleeve has been properly shifted and before the wire line tool has been removed from the hole.

As mentioned above, the shifting tools shown in the above applications have a dog which is frangibly mounted on the tool to push the sleeve up wardly after which the mounting is severed to retract the dog and release afdownwardly facing dog which can engage the sleeve to move it downwardly. With such a tool and when a plurality of sleeves are to be manipulated in a well, all upward shifting of the sleeves must be serially from top to bottom and all downward shifting from bottom to top. It would be highly desirable to possess such a shifting tool having an improved mechanism permitting alternate retraction and extension of the dogs any number of times while the tool remained in the well so that sleeves could be shifted in any direction in any desired sequence.

It is an object of this invention to provide a tool for.

" the first dog while the second part is moved by manipulation of a wire line or other means whereby the action of the 'tool is made positive and notfsusceptible of failure.

Another object is to provide a tool of such type in which a plurality of dogs can be employed to engage a valve means or other member to hold one tool part against movement while the other tool part is being moved by a wire line, there being provided ,a releasable means restraining relative movement between such parts until a predetermined moving force has been applied. to the other tool part, whereby at least such force is always applied to the valve means or other member, evensitely facing first and second dogs alternately operable to" shift the member in opposite directions and a mecha r nism for moving one dog to retracted position while "releasing the second'dog and then, without removing the tool from the well, retracting the second dog while releasing the first dog so that the shiftable member can be shifted upwardly and downwardly any desired number of 1 times or a plurality of such members can be shifted 'as desired in any sequence, all without removing the tool from the well. I p

Another objectis to provide a wire line toolhaving oppositely facing dogs respectively engageable with oppositelyfacing abutments in a well to limit movement of the tool past such abutments and arrangedso that the respective dogs permit free movement of the tool away from the respective abutments engageablethereby, there also being provided means for alternately retracting the dogs any number of times while the tool is inthe well o; that the tool can selectively engage a plurality ofabut- V 'ments in a well in any desired sequence during u ward tool in thewell to permit j 4 3' or downward movement of the tool in the well or during any desired sequence of both such movements.

The sleeve can then be lowered and will retain the pin. In Fig. 2A, pin 34 is shown sheared and, if desired, knockout holes 40 can be disposed in the body portion 24 to permit the part of the pin in body portion 25 to be easily removed and a knockout hole 41 can be disposed in body portion 25 to permit the two pin portions in body portion 24 to also be knocked out.

In order to prevent relative rotation between the two body parts, a lock pin 42 can be disposed in body part 24 with a portion thereof sliding in a slot 43 in body part 25.

Referring now to Figs. 4, '5, and 6, there is shown a well conduit 50 having ports 51 therein controlled by a shiftable valve means or a sleeve 52. The sleeve has an imperforate-portion 53 so that when it is in its lowremost position, this portion blocks flow through ports 51. The sleeve also has ports 54 adapted, .when the sleeve is raised to its upper position, to register with ports 51 to permit fluid flow between the interior and exterior of the well conduit. The'sleeve is free for movement between two positions as shown in Figs. 4 and 5.

The tool of Figs. lA-lB is shown in elevation in Figs. 4, 5 and 6 as suspended from a wire line 55 via a set of wire line jars 56. With the parts of the tool positioned as shown in Figs. 1A and 1B, the shifting tool can be lowered through the well conduit until it reaches a point below sleeve 52. Thereupon, upward move ment of the tool permits dogs 15 and 15a to move out and engage the lower end 57 of sleeve 52. Continued upward force applied by wire line 55 will cause the sleeve to move upwardly, aidedby jarring action if desired. After the sleeve has been moved upwardly to its Fig. 5 position, an added upward force on the wire line will cause shear pin 34 to shear so that the parts of the tool assume the Pigs. 2A-2B position. This retracts the upwardly facing dogs and permits the downwardly facing dogs 1616a to move to extended position Where they are free to engage the upper end 58 of sleeve 52 to limit movement of the shifting tool downwardly. Thenby jarring downwardly with the wire line, the sleeve can be moved back to its Fig. 4 position if desired. Of course, after this operation has been completed, the shifting tool can be moved upwardly through the well conduit to engage the upper ends of any succeeding sleeves thereabove,

While only one sleeve has been shown in the conduit of Figs. 46, a plurality of these sleeves can be spaced at various depths along a well conduit. Then the shifting tool can be lowered to move one or more of these sleeves upwardly by working from the topmost sleeve toward the bottom. After the bottom sleeve has been shifted, the upwardly facing dogs can be retracted and the tool then employed for downward shifting of the sleeves serially from bottom to top.

It will also be seen that the tool of this invention can employ a plurality of dogs although only two have been shown in the drawings. By the use of a single shear 'pin to govern retraction and extension of the dogs, there will always be required at least a predetermined force to cause such retraction and extension even though the upwardly facing dogs may unevenly engage the sleeve. Thus, for example, when using a pair of upwardly facing dogs, if only one of them should for some reason engage the sleeve, it still requires the same upward force on the wire line to shear pin 34 as it would if both dogs were in equal engagement with the sleeve. As a result, one can be assured that at least such predetermined force is applied to the sleeve to shift it upwardly and by making shearpin 34 of a size thattheforce to shear it is always greater than that required to shift a sleeve, thesleeve will always 'positivelyfbej shifted upwardly before the upper dogs vare retracted.

With the tool as just specifically described, it will be seen that once the downwardly facing dogs are moved to extended position, it is not thereafter possible'toi move asleeve upwardly without first removing the tool from the well to replace the shear pin. With the arrangement of Fig. 7, the upwardly and downwardly facing dogs can be alternately retracted and permitted to move to extended position as many timesas maybe desired without removing the tool from the well. [In

this arrangement, the shear pin of Figs. 1A and 1B is" replaced by a latch ring 60 carried within-a sleeve "61 forming a depending extension from housing part 25. Ring 60 has inwardly extending tapered portions 62 and v 63 adapted to engage a groove 64 in asplitspring ring 65. With this arrangement, the lower dogs 16-16a will be held in retracted position until enough upward force is applied on body part 25' by thewire line'to cause the splitting 65 to be .contracted inwardly to release portion 62 and ring 60 for'upward movement with body part 25. As soon as the body part 25 has moved upwardly sufficient to release dogs 16 -1 6a' and retract dogs 15-- 15a, portion 63 will enter groove 64 to limit further upward movement. By applying a downward force on body part 25 while holding bodypart 24, the above action is reversed. part 25 can be shifted axially in eithe'rfdirec'tion with respect to body part 24 to alternately retract the Yup-. wardly and downwardly facing dogs as many times as may be desired. In connection with this, it will benoted that the upper ends of dogs 16 and 1611 have a tapered portion 35a engageable with; a ring 30a .which moves the dogs into and holds them in retracted'position;

Both rings 30v and 30a are urged towardshoulder stops- 66 and 67 respectively by spring 32 so that the spring can be compressed by movement of body part 25 to sub-i sequently retract one pair of dogs whenthe latter are too tightly engaged during movement of ,body,part 25 to then permit their retraction. V

In. order to tassist sleeve 60 and'ring the body parts in one, position or ,theother untilta. de-- sired force has been applied to cause them to shift, spring 132 is disposed between two-releasable detent members comprising rings 68 and 69'slidable 'on body part25 and engage shoulders 72 and 73 when the body part 25 is in its downmost and uppermost positions. With this construction, the accidental application of excessive force tending to COntIfiCtfIing 64 and permit body part 25 to prematurely move upwardly is opposed byforce exerted I by spring 32 which in eifect is added tothe upward force required to contractring 65. If desired, the spacing between portions 62 and 63 can be made slightly greater than the spacing-between the adjacent ends of latch fingers 70 and71 so .that the end of one latch finger engages the end of the other to dislodge it from its engage-H;

ment with portions 72 or 73 before body part 25 has undergone its complete movement whereby the engage- A ment between thelatch fingers and portions :72 and 73 can be made very firm and spring 3-2 of considerable. strength. This helps prevent premature" movement of body part 25.

Referring now. to Figs..8 and 9, there is shown a which can be formed as apart of the shifting tool, of Figs;

In explaining the operation of the assembly of Figs. 12 and 13, assume that sleeve 113 is in its uppermost position and is to be shifted downwardly. The locator tool, spacer bar and shifting tool are assembled on a wire line as shown in Fig. 12 and lowered into the well conduit with dogs 15 and 15a of each of the shifting tool and locator tool being free to move to extended position. As soon as the shifting tool reaches a position below the sleeve, it is pulled upwardly until its dogs 15 and 15a engage the lower end of the sleeve. An additional pull will then causethe shear pin in the shifting tool to shear (or the two-way detent to be released) whereby dogs 15--15a arevretracted and the downwardly facing dogs 16-16a are permitted to move to extended position. The tool is then pulled upwardly in the well until dogs 15- 15a of the locator tool engage the lower end of the sleeve and an additional pull exerted to retract dogs 1515a of the locator tool and permit dogs 16c16d to move to extended position. The tool is then lowered back down the well until dogs 16-1611 of the shifting tool engage the upper end of the sleeve and then jars 56 can be actuated to shift the sleeve downwardly. As soon as the operator thinks that thesleeve has been properly shifted downwardly, he can pull up on the wire line a distance such that dogs 16c-16d will be above the sleeve. Then upon lowering the wire line, dogs 16c-16d will move outwardly into the recess between the sleeve and conduit portions 119 and 120 to engage the upper ends of the sleeve as shown in Fig. 13. The operator will then note a slackening on his wire line and can be assured that the sleeve 113 has been properly shifted.

' Should the sleeve 113 not have been shifted sufficiently far downwardly, dogs 16c-16d will bridge between sleeve and conduit portions 119-120 and permit the locator tool to move downwardly again through the sleeve. This excessive downward movement will indicate to the operator that the sleeve has not been shifted,

downwardly to its proper position. He can then continue lowering the tool until the downwardly facing dogs of the shifting tool again engage the sleeve to repeat the operation.

The various shifting tools of this invention can be combined with the locator tools and holding tools to provide various combinations as will be apparent to one skilled in the art.

From the foregoing it will be seen that this invention is one well adapted to attain all of the ends and objects hereinabove' set forth, together with other advantages which are obvious and which are inherent to the apparatus. v

It will be understood that certain features and subcombinations are of utility and may be employed with- -out reference to other features and subcombinations.
